Question

curb gem无法安装。我正在使用以下配置： -

Windows 7
Ruby 2
Rails 4
gem“bundler 1.3.5”

C：\ RorProjects＆gt; gem install curb

构建原生扩展。这可能需要一段时间...... 错误：安装路边错误：错误：无法构建gem原生扩展。

    C:\Users\abc>gem install curb

  Try passing --with-curl-dir or --with-curl-lib and --with-curl-include
  options to extconf.

尝试安装mingw并在其中运行命令，我还没有在Windows上工作一段时间，但它曾用于修复我的gem安装问题：

Answer 2

您必须指定头文件和静态库的路径才能构建扩展。首先确保安装了ruby devkit。然后download x86包（后缀'devel'，它是包含所有内容的那个），在某处提取并尝试gem install curb -- --with-curl-lib=c:/path/to/curl/lib --with-curl-include=c:/path/to/curl/include。

如果这个不起作用（对我来说，当我尝试使用libcurl 7.32.0和ruby 2.0安装curb时没有），你可以尝试下载x86 libcurl包here，按照说明操作在第一篇文章中提取它，设置环境然后运行gem install curb -- -with-opt-dir=c:/path/to/libcurl。这让我在这篇文章的时候遏制了0.8.5。
